To all whom it may concern.-

Be it known that I, EUGENE W. SILsBY, a citizen of the United States, residing at Lagrange, county of Cook, and State of Illinois, have invented certain new and useful Improvements in Die-Presses, of which the following is a specification, reference being had to the accompanying drawings, formingapart thereof.

The purpose of this invention is to produce a simpler construction of a die-press than has been heretofore employed, especially with reference to operations requiring two processes and in presses having for that purpose two dies on the bed or on the reciprocating head. I have shown theinvention in a press with the .two dies on the bed; but it will be obvious that it is immaterial which member carries the two dies and which carries the one adapted to cooperate with the two alternately.

The invention consists in the features of construction which are specified in the claims.

In the drawings, Figure 1 is a partly section al side elevation of my improved press,the bed and stand being shown in section on line 1 1 on Fig. 2. Fig. 2 is a plan of the same. Fig. 3 is a detail rear elevation, showing the devices for oscillating the reciprocating member.

In general my improved press comprises a fixed bed having an upright post through which a vertical shaft reciprocates, such shaft havingat the upper end a radial arm which extends out over the post, overhanging the bed, and carryinga die, the lower end of the shaft below the bed being connected with suitable means for operating it-as, for example, a pedal to depress it, with suitable spring to elevate it. In addition to these general features it comprises means for oscillating the diecarrying arm attached to the shaft by turning the shaft in its bearing in the post so as to cause it to descend alternately along two paths, so as to cooperate alternately with the two dies on the bed.

A is the bed of the press.

A is the supporting-stand.

B is a post erected rigidly from the bed.

0 is a shaft reciprocating vertically through the post, having at the upper end a short radial arm 0, extending out over the post, overhanging the bed, and carrying a die, (conventionally represented at D.)

E and E are two dies on the bed, both at the same distance from the reciprocating shaft, so that the die D may cooperate with either of them, according to the position in which it is reciprocated.

K is a pedal suitably connected to the shaft below the bed to reciprocate it; K, a spring which retracts the pedal and the shaft upward. Any suitable means for reciprocating the shaft may be substituted for these familiar elements. 7

In order to control the path of reciprocation of the shaft so as to cause the die 13 to register properly with either the die E or the die E, according to the stage of the work, I make two parallel slots B B in the post 13, leading into the hearing or chamber about the shaft 0, and I provide the shaft with a rigid stud G which projects through the bearing and may be engaged in either of the slots and when thus engaged guides the shaft vertically according to the trend of the slot, and said slots being at their lower portion both vertical the shaft is caused to move with a direct vertical movement during such portion of its reciprocation as is occupied by the necessary cooperation of the dies in performing their work. Toward the upper part the two slots B B merge together, each trending equally toward the other and the aperture continuing as a single slot 13* for a short distance above the apex b of the metal intervening between the slots at their merger. The extension B of the joined slot is wider than either one,but not necessarily so wide as their sum, for reasons which will be apparent as the description of the cofiperating elements proceeds.

For the purpose of diverting the stud C from the line of either slot along which it rises over toward the line of the other slot, so that it may descend in the latter, and thus be caused to alternate between the two slots and cause the die carried by the shaft to cooper ate alternately with the two dies on the bed, I provide switch devices, consisting of levers F F,which are fulcrumed to the standards and most conveniently on lugs B B jutting off from the post B at opposite sides,said f ulcrums being symmetrically disposed with r speet Po the slots B 13' and farther ill-721K313 1. an Sa1 1 the end of the stud as it projects through one slot or the other trend downward toward each other. The stud O terminates in a spherical head 0 which is wholly outside the post, the neck of the studthat is, the portion back of such head-being long enough to extend through the shell of the post, and the free ends of the levers F F are each formed with a spherical cavity or socket adapted to fit the spherical head of the stud. A spring G is connected to both the levers, connecting them together, the points of attachment of the spring being such that when they are in line with the axes of the lever-pivots the spherical sockets at the ends of the levers, respectively,are in position directly overhanging the path of the spherical knob C which terminates the stud C The tension of the spring, it will be understood, tends to hold the levers in this position by drawing the two points of attachment of the spring into line with the pivot-axes of the levers, and the action of the spring tends, therefore, to restore the levers to this position whenever they are disturbed therefrom in any direction. It will now be understood that if the shaft has been deand upon such an encounter, the spherical socket at the end of the lever engaging the stud, the lever will be swung over toward the opposite slots as the shaft and stud continue -to rise, and in so doing the stud itself will be forced over toward the other slot, thus rolling or turning the shaft in its bearings. The position of the pivots of the levers and their trend are such that during the upward movement of the shaft, which occurs after the en'- counter of the stud with either of the levers, the lever will be swung over far enough-to carry the stud past the center of the interval between the two slots-that is, over beyond the apex b'-so that upon the descent of the shaft the stud will encounter the slope leading from said apex toward the opposite slot from that in which it ascended, and it will be guided over into said opposite slot and will make its next trip downward controlled in its path by such slot, causing the die carried by the shaft to cooperate with the opposite die on the bed. In swinging up to the position described the first lever will have passed over the end of the opposite lever, and the stud in descending will encounter said opposite lever, which will yield aside to allow the stud to pass it in its downward course, the spring G tending equally to retract the lever when it is thus forced outward as when it is forced inward by the encoun er of the Stlld in its ascent. when the sbu n xb ris as, the opera.- tion will be repeated, but In the Inverse order,

the lever which was encountered during the descent of the stud and forced aside outward being now encountered on the under side and swung inward and operating to carry the stud inward over toward the other slot and above the point of the other lever. Since the stud in passing from side to side in the manner described movesiu the arc of a circle about the axis of the shaft, it is necessary to provide a construction which will permit the levers to conform to this path at the same time that they swing inwardthat is, each toward the other-to cause the shaft to be thus turned. For this purpose I make the pivotal connec tion of the levers to the standard by means of a stud F, which extends horizontally into the standard and turns therein,being retained by a cotter-pin f at the forward side of the lug B to which the lever is pivoted, and the lever itself is hinged tothis stud at the opposite side of the lug, so that it is adapted to swing toward and from the post. This constitutes practically a universal joint and allows the lever to accommodate itself to the curved path of movement of the stud as the latter turns with the shaft. By attaching the spring G to the levers at a short distance below the pivot of their hinged connection to the studs F F, respectively, the spring is made to operate not only to swing the levers inward toward each other in the manner described and necessary for their functions, but also to swing them inward toward the post, and thus to retract them after they are swung outward from the center of the post by the curvilinear movement of the spherical head of the stud. The same spring thus operates to hold the levers yieldingly toward each other and to hold them yieldingly in toward the center of the post.

When a press is employed in the manner here indicated-that is, the article partly formed in the first die being completed in the operation of the second diesuch article may require to be ejected from the latter die, and it is desirable to eject it automatically, and dies having this purpose are provided with an element suited to eject the article upwardly.

IIO

The particular construction of the die or of i this ejecting element is not material for my present purpose; but in order to perform this ejecting operation I provide-the ejecting-element of the die with a downwardly-projecting terminal rod D and on the shaft 0, below the bed, I mount an ejecting-arm H, having a hub H, by which it is carried on the shaft looselythat is, free both to turn and move longitudinally with respect to the shaft. It is stopped on the shaft by a pin 0, extending through the latter, and the hub has a notch 72, with sloping sides, in which the pin rests, the arm resting on the pin by gravity and being free to turn about the shaft, but compelled to move upward on the shaft when it is turned by reason of the sloping sides of the notch h, in which the pin 0 is engaged. The arm H has thus a definite position in the plane of its possible rotation about the shaft 0, to which it will return if disturbed only slightly-that is, less than the range of the notch h. The position of this arm as thus determined is such that as the shaft descends for cooperation of the upper die with the first of the lower dies the arm H moves up and down atone side of the ejecting-rod D and without action thereon; but as the shaft rises after this first downward movement and the stud C encounters one of the levers and is moved laterally, rotating the shaft, the arm H is swung over, so that it bears against or stands close to the side of the rod D and as the shaft descends and is further turned in the same direction by the encounter of the stud with the slope of the slot leading from the apex b the arm H is pressed against the side of the rod, and being restrained thereby and unable to turn farther in that direction the continued turning of the shaft causes the arm to be lifted relatively to the shaft by the cooperation of the pin 0 with the slope of the notch h, and in such position it continues to move as the shaft descends, sliding down along the side of the rod D until it passes below the end of the latter, whereupon by the action of gravity, being free from the lateral restraint of the rod, it returns to its normal position with respect to the shaft, the pin 0 reaching beyond the apex of the notch 72', the arm rotating on the shaft back to its normal position, and in so doing passing under the end of the rod D so that when the shaft rises it encounters the rod and thrusts it upward, ejecting from the die the article formed therein. At the upper limit of.

this return stroke the turning of the shaft in its bearing in the opposite direction carries the arm H out from under the end of the rod D and permits the lever to regain its normal position.

When this press is used with a die carried by the head, havinga yielding member which is to be held unyielding during the cooperation with one of the dies on the head and permitted to yield to cooperate with the other bed-die, havingfor that purpose a latch which locks the two members together during the first operation and which must be released for the second, I employ an expedient for eifecting this change, which I will now describe.

D represents a yielding member of the die D. A latch in the form of a rock-shaft D is pivoted to the unyielding part of said die and has a short lever-arm D at the lower end, constituting a nose held in engagement above the shoulder D of the yielding member D by a spring D coiled about the rock-shaft and suitably stopped against and on the bearing, thus locking said yielding member rigid with the remainder of the die. A lever-arm D at the lower end of the latch-shaft, ex-

tending ofi toward the post B, acts as a triptail, cooperating with the boss B on the post. This boss isv entirely out of the path of the tail D when the die D descends to cooperate with the first die on the bed-that is, the one with which its cooperation requires that the two members of said head-die should be rigid; but as the shaft D is oscillated and the die D is carried over toward its second position the tail D encountering the boss, causes the latter to be rocked in its vertical bearing and the nose D to be disengaged from the shoulder D and to be held thus disengaged while the die travels down along its second path, thus leaving the yielding member of the die free to yield upward as may be required for its proper cooperation with the second beddie. During the return of the head-die to its original position the tail D of the latch travels back over the face of the boss B and running 06 the same recovers its original position, the nose D rengaging the yielding member D and locking same rigid with the fixed member, making the die ready to descend for cooperation again with the fixed die.
